Abstract: A gyroscopic system and method is provided for translating parallel and non-parallel lines between a reference line and a device to be aligned with respect to the reference line. A first inertial sensor is provided that is configured to be substantially stationary. This inertial sensor is boresighted with respect to the reference line and includes at least two gyroscopes and a mirror having first and second nonplanar surfaces. A second, portable inertial sensor is provided that includes a gimbal, a gimbal drive system, an electronic energy beam generator, a collimator, and at least two gyroscopes. One or more of the electronic beam generator, collimator, and gyroscopes can optionally be mounted on a platform that is mounted on the gimbal and adapted to move in accordance with signals from the gimbal drive system. A control circuit is provided that is operable to measure output signals generated by the first and second inertial sensor gyroscopes and to determine relative orientations of the inertial sensors.

Abstract: A cryogenic probe is disclosed comprising a barrel having a plunger mechanism movably mounted therein and having a valve on the lower end thereof. The valve normally closes the lower end of the barrel but the plunger may be moved relative to the barrel to permit cryogenic liquid such as liquid nitrogen to by-pass the valve and to move upwardly into the interior of the barrel. The valve has a tip portion at the lower end thereof. The barrel is removably positioned in a guard so that the tip portion extends outwardly through the bottom of the guard and so that the upper end of the plunger is exposed above the guard. The tip portion has a lower end portion which is extremely thin so that the cryogenic liquid will be positioned closely adjacent the skin but not in actual contact therewith when the tip portion is placed into contact with the patient's skin. The method of charging the device is disclosed as is the method of using the same.
